EON Secures $10.75 Million to Connect Global Data Centers via Orbital Lasers

Startup Endeavor Optical Networks (EON) has emerged from stealth with $10.75 million in seed funding to develop an orbital laser satellite network. The company aims to connect global data centers using space-based optical communication, offering a high-capacity alternative to undersea fiberoptic cables.

What Happened

Endeavor Optical Networks (EON), founded in May by CEO Charlie Horowitz and CTO Tyler Presser, announced $10.75 million in seed financing. The funding round was led by General Catalyst and Andreessen Horowitz, with personal investment from Apex Space CEO Ian Cinnamon. EON plans to utilize the capital to build an optics laboratory, hire additional engineers, and conduct ground testing ahead of a demonstration satellite planned for launch around the end of 2027.

The startup aims to resolve significant global data transmission challenges. Hyperscalers currently rely on a brittle network of undersea fiberoptic cables that are difficult to access, install, and repair. Conventional ground and orbital radio transmissions lack the bandwidth required for massive data center transfers. EON intends to use laser-equipped spacecraft in orbit to transmit data directly between continents.

Key Highlights

• Seed Round Funding: EON raised $10.75 million led by General Catalyst and Andreessen Horowitz.
• Planned Satellite Network: The company aims to build a fleet of approximately 20 satellites to provide 24-hour coverage and dedicated intercontinental links.
• Data Throughput Goals: While conventional undersea cables carry 200 terabits per second (Tbps) and previous satellite laser tests achieved 2.5 Gbps, EON is aiming for an initial capacity of 2.4 Tbps. Its 2027 demo satellite aims for 800 Gbps to 1 Tbps downlink speed.
• Hardware Strategy: EON will manufacture custom optical communications terminals—focusing on precise pointing gimbals—while purchasing off-the-shelf satellite busses from manufacturers such as Apex Space.
• Target Market: Customers include hyperscalers and artificial intelligence labs needing dedicated capacity across long or expensive routes, such as France to Australia or Africa to South America.
• Experienced Leadership: EON’s technical team includes CTO Tyler Presser (former NASA mission planner), Michael David Francois (former Google global infrastructure executive), and Wesley Baxter (former Amazon LEO satellite optics engineer).

Why This Matters

Hyperscalers and artificial intelligence laboratories move unprecedented amounts of data across the globe, straining current terrestrial and subsea infrastructure. Subsea optical cables are critical but vulnerable to physical damage and complex repairs. Radio frequencies cannot handle the multi-terabit bandwidth requirements modern facilities demand.

A major obstacle for space-to-ground laser communication is atmospheric distortion, particularly cloud cover. To maintain continuous service, EON plans to strategically place ground stations using localized weather data and redundant sites. Commenting on the broader market, Caleb Henry, director of research at Quilty Space, noted that while satellite internet is evolving into dependable high-bandwidth infrastructure, satisfying strict data center redundancy standards remains a complex challenge. EON also faces competition from larger initiatives, such as Blue Origin’s proposed 5,048-satellite TeraWave network aiming for 6 Tbps throughput.

What to Watch Next

EON will focus its initial capital on setting up its optics lab, expanding technical staff, and conducting ground-based test operations. The primary future milestone is the launch of its initial demonstration satellite, slated for around the end of 2027, to test orbital high-speed laser downlinks.

Frequently Asked Questions

Who founded EON and who are its financial backers?
